A dust filter 200 is disposed at a rear end of the front end filter 140 and a dust filter 200 is disposed at a rear end of the dust filter 200. [ The carbon filter 150 is installed close to the air outlet 112.

Further, although not shown in the main body 110, a separate suction fan can be installed, and the suction fan can be connected to an apparatus having a suction function.

The front-end filter unit 110 may be provided with a grease filter alone or with a grease filter and a pre-filter at the same time. The grease filter filters the retained components in the contaminated air, and the pre-filter collects large dust give.

The dust filter 200 includes a high pressure generating part 210 for generating a negative charge of high pressure and a dust collecting filter 200 for collecting fine dust particles closely attached to the rear end of the high pressure generating part 210, And a dust collecting unit 220.

4, the high-voltage generating unit 210 includes a first electrode 211 in the form of a rim and a second electrode 212 in the form of a strip with electrode pins between the first electrodes, A high voltage is applied between the first electrode and the second electrode to generate a negative charge, and the dust particles introduced by the negative charge are adhered to the dust collecting unit 220.

The dust collecting unit 220 includes a collecting grid portion 221a and a collecting dust collecting portion 222a in which the first collecting portion 221 and the second collecting portion 222 are connected to each other in the same shape, A handle 221b or 222b which can push or pull the motor 220 in the left or right direction and a rail groove 221c or 222c which is seated on the rail part 240 as a bottom surface.

The dust collecting unit 220 is formed in the collecting grid units 221a and 222a in an electrostatic matrix structure in which a negative electrode and a positive electrode power source are vertically applied to the collecting grid units 221a and 222a, Are stuck between the trapping grid portions 221a and 222a.

Thus, dust particles are trapped and the bacteria and microorganisms that stick to the dust particles are removed by the electric field and pure air is circulated.

5, the dust collecting unit 220 includes two first and second collecting units 221 and 223, and is formed below the first and second cleaning chambers 120 and 130, When the first collecting part 221 is tightly coupled to the high pressure generating part 210, the second collecting part 222 is positioned in the second cleaning chamber 130 And can be cleaned by a cleaning operation to be described later.

6, a plurality of spray tubes 120 and 130 formed at one side of the first and second cleaning chambers 120 and 130 are connected to the first and second cleaning chambers 120 and 130, The washing chamber 130 is connected to the spray nozzles 126 and 136 so that high pressure air is injected through the spray nozzle 126 to clean the collecting grid 121a of the first collecting unit 121, Thereby removing the dust particles sandwiched therebetween.

At this time, in the case of the first cleaning chamber 120, the removed dust particles are discharged to the outside via the suction pipe 123 through the lower drain hole 125 and the inclined portion 122.

A suction pump (not shown) is further installed at the other end of the suction pipe 123.

As shown in FIG. 2, a pair of optical sensors are installed inside the main body 110 in front of and behind the dust filter 200.

The optical sensor includes a light emitting portion 231 and a light receiving portion 232 and detects the amount of dust particles sandwiched between the trapping grid portions 221a and 222a of the dust collecting portion 220.

The light emitting unit 231 irradiates the light receiving unit 232 with a predetermined amount of light. Therefore, a constant amount of light is received by the light receiving portion 231.

However, when dust particles are gradually accumulated in the trapping grid portions 221a and 222a, the amount of light received by the light receiving portion 232 is reduced.

The degree of blockage of the trapping grid portions 221a and 222a is determined according to the amount of light received by the light receiving portion 232. When the collected grid portions 221a and 222a of the received light amount are more than a set value required for cleaning, .

Therefore, the manager recognizes the cleaning timing of the trapping grid portions 221a and 222a through the alarm sound.

The carbon filter 150 performs a function of removing residual radicals and other unspecified odors in the air.

Reference numeral 113 denotes an open door, and 114 denotes an operation chamber.

Hereinafter, the overall operation and operation of the malodor removing apparatus having the cleaning function of the dust filter of the present invention will be described.

First, the air inlet 111 of the malodor removing apparatus to which the present invention is applied is connected to the inner duct (deodorizing) structure of the building, and the air outlet 112 is installed to face the outside of the building.

Thereafter, the opening door 124 provided in the first washing chamber 120 or the second washing chamber 130 is opened and the first collecting portion 221 or the second collecting portion 222 of the dust collecting filter 200 And one of them is brought into close contact with the high-pressure generating portion 210.

This operation is performed by using the first collecting portion 221 or the second collecting portion 222 with the rails 121 and 131 provided on the sides of the first collecting portion 221 or the second collecting portion 222, 240, respectively.

Then, the suction fan for suction, which is not shown, is driven to operate the malodor removing device.

Accordingly, the air including the odor and fine dust generated in the building through the air inlet 111 flows into the front end filter unit 110.

At this time, the air introduced into the front-end filter unit 110 filters a retained component by a grease filter, and dust having a large particle size is collected by the pre-filter.

The fine dust and odor components passing through the front end filter unit 110 flow into the dust filter 200.

The dusts introduced into the dust filter 200 are attracted to the negative charge by the high pressure generator 210 generating the negative charge of high pressure and then moved to the selected first collector 211 of the dust collector 220.

The dust particles transferred to the first collecting portion 221 are stuck between the collecting grid portions 221a.

Therefore, the dust particles are collected in the trapping grid portion 221a, and the bacteria and microorganisms attached to the dust particles are removed by the electric field, and pure air is circulated.

The purified air passing through the dust filter 200 is passed through the carbon filter 150 once more to finally remove excess radicals and other unspecified odors in the air to remove fine dust from the air outlet 112, Thereby discharging the air that has been removed.

In performing such an operation, the optical sensors provided in front of and behind the dust filter 200 perform a function of detecting the amount of dust particles sandwiched between the trapping grid portions 221a of the dust collecting portion 220 .

Accordingly, when the cleaning of the trapping grid portion 221a is detected as a set value required by the optical sensor including the light emitting portion 231 and the light receiving portion 232, It gives an alarm to let you know.

Therefore, in order to clean the collecting grid portion 221a, the manager suspends the operation of the malodor removing device, opens the opening door 24 of the first cleaning chamber 120, pulls the handle 221b, So that the collecting part 221 is located in the first cleaning chamber 120.

At this time, the second collecting part 222 is naturally positioned close to the high pressure generating part 210.

When the movement of the dust collecting unit 220 is completed, the open door 124 is closed and the operation of the malodor removing apparatus is resumed.

Therefore, the function of the dust filter 200 functions as the high-pressure filter unit 210 and the two dust collecting units 222 of the dust collecting unit 220.

At the same time, air is injected into the plurality of spray tubes 120 of the first cleaning chamber 120.

Accordingly, high-pressure air is injected through the injection nozzle 126 formed at the tip of the injection tube 120, and the dust particles sandwiched between the trapping grid portions 121a of the first trapping portion 121 fall off at a high pressure .

At this time, the removed dust particles are discharged to the outside through the suction pipe 123 through the drain hole 125 and the inclined portion 122 of the first cleaning chamber 120.

When the cleaning operation is completed after a predetermined time, the air injection and the driving of the suction pump are stopped, and the malodor removing device continues to perform normal driving.

According to an embodiment of the present invention, when cleaning by the clogging of the dust filter is required, the manager manually moves the dust collector of the dust filter and performs the spray operation. However, it is known by those skilled in the art something to do.

As described above, according to the present invention, the dust collecting filter is provided to improve the ability to remove fine dust and odors, to automatically detect the clogging of the dust collecting part of the dust collecting filter, and to clean the dust collecting part when the clogging is detected to exceed the set value, So that the malodor removing operation can be normally performed even during the sub-cleaning.
